| Abstract |
This paper exposes the feasibility to connect high
voltage dc transmission (HVDC) systems to very weak ac
networks leading to short circuit ratios (SCR) lower than
1.5. The existing literature does not provide solutions for
such a low SCR systems and often the HVDC expansions
cannot grow enough as expected. The studies developed are
for the short-term voltage stability phenomena, where a
solution using the PSCAD/EMTDC program for a very
weak ac network with SCR = 1.0 is presented. The reactive
power characteristics are shown since they are important to
judge the behavior of solutions for ac/dc interactions. |
